Demartek performs lab validation testing on a variety of server, networking and storage products,
with an emphasis on real-world applications and end-to-end configurations. We provide reports on
our website that show performance results including graphs to help describe the results.

Client Web Browsers and Operating Environments

Although the Demartek website does not use cookies and we do not track individual users, we can
gather aggregate statistics (stats) about the client computing devices that visit our website. This
is based on data that the client browser provides about itself. Technically, one could alter their
browser to make it appear to be a different browser than it really is, but most people use their
browser without making such a change.

The data we show below is from our own website logs. Because our website content is focused on
enterprise IT technology, our data will differ somewhat from the larger market-share reports where
consumer and enterprise users are often lumped together.

Exclusions from the web server log data

The charts below show the client browser usage statistics for the previous month. We filter our web logs
before providing any statistics. Activity excluded from these statistics include:

Web crawlers and other “bots”

Accesses from within Demartek offices

We filter out our own accesses from the data shown below, so as not to skew the results. We typically
receive more than ten thousand hits per month by real humans on our website.

November 2016 Statistics — Client Web Browsers

At Demartek, different people use different browsers as their primary browser, including
current versions of Internet Explorer, Firefox and Google Chrome. Some of us here at
Demartek have been known to use more than one type of browser.

We know that some corporate environments require specific versions of browsers that may
not be current, so we have attempted to make our website provide a consistent experience
with certain older browsers. The statistics shown in the chart below include all versions
of each browser.

Web Browser Recommendations
We recommend Internet Explorer (IE) 9 and above, or any recent version of Firefox or Chrome.

* The Chrome and Firefox browser development teams have implemented a “rapid release” schedule,
where new versions are released approximately every six weeks. Some corporate environments that
require testing of their environments before deploying new software may choose not to deploy
every new version of these browsers.

The “other” (...) category includes some site-specific browsers and browsers that are specific to smartphones
and tablets, such as Android, BlackBerry, etc. We try to filter out as many of the web crawlers and bots from
these statistics as possible, but there seems to be an endless variety of web crawlers and bots roaming the Internet.

November 2016 Statistics — Client Operating Environments

Because our website primarily serves business customers and end-users, the predominant method that people
use to access our website is via a desktop computer or server, rather than a portable consumer device such
as a smartphone or tablet. The chart below shows that the vast majority of people who visit our website are
using a desktop version of Microsoft Windows. A small percentage of users access our website from smartphones
and tablets. As of April 2015, due to the high frequency of "bot hits", we will be excluding operating systems
older than the year 2000.

It is great to see a monthly update of how our business customers and end-users are accessing our site, but
that is a small part of the big picture. Browser and operating systems are constantly changing and we are
interested in the gradual shift that is occurring when viewing our site.

Most of our visitors are accessing our site through a version of the Windows operating system. We thought it
would be interesting to show separate versions of Windows to see the flux in popularity for each operating system.
We are now tracking Windows 10 usage.
